“…Hollow rollers possess better lubrication, lighter weight and high rotational speeds than the solid rollers. Many researchers have found that hollow rollers have longer fatigue life than solid rollers (Somasundar and Krishnamurthy, 1984; Abu-Jadayil and Flugrad, 2007).…”

Purpose The purpose of this paper is to develop a mathematical model to determine optimum hollowness of a layered cylindrical hollow rolling element when it contacts with a flat plate. Design/methodology/approach In this work, finite element analysis (FEA) is carried out for different hollowness percentages ranging from 10 to 90 layered cylindrical hollow rolling elements corresponding to five standard NU 22 series bearings, i.e. 2206, 2210, 2215, 2220 and 2224. An experimental investigation is carried out for the NU 2206-layered cylindrical hollow roller bearing (LCHRB) at optimum hollowness under static loading condition. Findings Different parameters, such as bending stress (von Mises stress at the bore of the roller), von Mises stress, contact pressure and deflection in loaded contact are presented here. Originality/value The value of this research work is the development of a generalized solution that can be used to find the exact value of optimum hollowness for the layered cylindrical hollow rolling element, which is dependent on the yield strength of the material and the geometry of the roller under static loading condition. A static load test rig is designed to observe the load carrying capacity of the LCHRB as compared to the hollow cylindrical roller bearing.

“…Because of the importance of the Ni-Ti composition in many engineering applications, many researches like Abu Jadayil and Flugrad (2007), Abu Jadayil (2008), Abu Jadayil and Jaber (2009), Abu and Abu Jadayil and Mohsen (2011) have been conducted to investigate the fatigue life of components made of Ni-Ti alloy. On the other hand, Abu Jadayil and Alnaber (2013) investigated the fatigue life of Ni-Ti samples prepared by different techniques.…”

The use of Ni-Ti alloy in medical applications gave a great importance for the right composition of this alloy and the method of fabricating this alloy parts. Medical implants should be tested to assure that there are no defects or imperfections included and so no harmful effects could take place. In this study different Ni-Ti alloy composition samples have been fabricated using three different techniques. These techniques are sand casting, powder-sand casting method and sintering method. A comparison between samples made in by each technique was made. Surface and subsurface defects found in these fabricated samples have been investigated using nondestructive techniques. These non-destructive techniques used were die penetrant testing, electromagnetic method and finally samples were inspected using ultrasonic waves. Based on the results of surface and subsurface nondestructive tests used, samples prepared using sand casting were found to have the lowest surface and subsurface defects and so it is highly recommended to fabricate Ni-Ti alloy implants.
